Getting the Client's Real IP Address

The real user's IP address has to be properly extracted from a request if your Wallarm node sits behind a load balancer or a CDN. For the Wallarm NGINX module to process the origin IP correctly, you have to add the set_real_ip_from and real_ip_header NGINX directives in your NGINX configuration file. This will ensure the connecting IP is being properly derived from an X-Forwarded-For header.
